%This example shows how to build a multiwalled camrbon nanotubes in three
%simple steps.

%First we create the inner CNT (type help cnt for options) 
inner = cnt(5,5,30);

%Below we create the bigger CNT
outer = cnt(10,10,30);

%The two MWCNT is created by simply summing the two structured 
CNT = inner + outer;

%The to visualize the structure we use the plot method.
CNT.plot;
